Description
Context
When using TEOS-10 Equation Of Seawater, there is a small bug in the calculation of the freezing point from Absolute Salinity (Sa) and pressure. The error is small (about 1.E-2) but not negligible. For example with Sa=35 g/kg and z=0, the current calculation leads to a freezing point of -1.9024 instead of -1.9115.
The error comes from a multiplication by a factor 0.875/35.16504 of the input salinity instead of 1/35.16504
Fix
in v3.6_stable (same modification in trunk) in both eos_fzp_2d and eos_fzp_0d replace the " * r1_S0 " by " / 35.16504_wp "
